Title:
SCROLL-TYPE COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2022/158198
Kind Code:
A1
Abstract:
[Problem] To reduce surface pressure acting on a tip end of a wind-ending part of a spiral wall of a revolving scroll in a scroll-type compressor. In the scroll-type compressor 10, a thrust plate 81 and an elastically deformable thrust sheet 82 are provided between an opposing surface 237 serving as a thrust-bearing part and a revolving substrate 521 of a revolving scroll 52. A first sealing material 83 creates a seal between the revolving substrate 521 and the thrust sheet 82, and a second sealing material 84 larger in diameter than the first sealing material 83 creates a seal between the thrust plate 81 and the opposing surface 237 of a second dividing wall part 232. A back pressure chamber H5 is partitioned off from a suction pressure region (space H6) by the thrust plate 81, the thrust sheet 82, the first sealing material 83, and the second sealing material 84. A circular recess 816 is formed in the surface of the thrust plate 81 on the side adjacent to the thrust sheet 82.
